The two (.com and commercial operators) aren't really connected.   From 
83 to about the early 90s, access to the internet  was permitted to 
commercial companies only under the AUP - which spelled out acceptable 
use and explicitly prohibited commercial use.  A number of companies 
involved in research and support of the internet (e.g. BBN who was 
BBN.com from about '87 or so ), were permitted access to support 
government programs, but not allowed to use it for their own 
purposes.    NSF's standing up of the various interconnect points, the 
NSFNet,  and a change in the routing to BGP allowed a commercial 
internet to rise up at the edges and various nationally based internet 
providers to interconnect.


(https://www.nsf.gov/od/lpa/nsf50/nsfoutreach/htm/n50_z2/pages_z3/28_pg.htm 
claims that the AUP was eased in '91).

Nope - it was under government control.  I remember approving at least a 
few interconnections during my time at the DDN program office (85-89), 
including a discussion with Vint that ended up getting MCIMail to be 
able to transit the internet.  I think Stewart is more correct than you.
